A gun chambered in 3" is plenty balistically to take care of whatever you need. These days you can buy as many varieties of loads for a 3" as you can effectively for a 3 1/2".

The effective range is a function of velocity and pellet size / 7 1/2's can have an effective range of 50 - 60 yards especially in 1 1/8 oz loads at 1300 fps ( Remington Nitro sporting clays load ). A load of 6's or 4's will hit a little harder at that range than 7 1/2's , for a given velocity, because of the size and weight of the shot. But you only need 1, maybe 2 pellets, of 7 1/2's to break a clay target at that range / so translating that to an effective kill range on a bird is very difficult - and beyond 40 yards, maybe its a shot you shouldn't take because it may not end with a clean kill.
